Noisy fans


my only concern with Manjaro on my new Dell is that the computer is very noisy even if do not have almost anything open. I suspect I might have turned on secondary graphic card. I have 16 thread CPU and most of them are barely used. Before I followed some tutorial and installed few packages and it was better but when I updated to gnome 3.36 (which is way snappier then previous) I needed to remove some of them because of conflicts. I can't find the tutorial neither I remember the package names. Can you help me?

Turning off skype was quite helpfull. It took constantly 35-40% CPU. I just do not understand that in System monitor in gnome I could not see it as most processes have 0%. CPU usage in top or htop seems very different

But I still would like to make it more quiet.

A couple of pieces of advice, in general for a new laptop: 1) Repaste the heatsink for both cpu and gpu, the factory paste job is often garbage and contirbutes to high temps which will make that fan go crazy. 2) With hybrid laptop graphics you are going to need to experiment and find a happy spot of both which graphics drivers you are using and when you are using that Quadro GPU. For most tasks that Quadro is not necessary and will contribute to higher temps and power drain. 3) Undervolt that cpu it will run cooler and extend battery life. ( I use it and it also works on some Dells. 4) Find a way to control your fan speed or create a custom fan curve. For Thinkpads you can use Thinkfan, I don't know if there is a similar item for Dells. 5) Accept your laptop is going to be a little louder you have an i9 cpu, not much you can do there.

As to System Monitor in Gnome make sure you have All Processes selected otherwise it will only track processes you initiated by default, also make sure it is sorting correctly.

Hope that helps. Good luck.

Thanks @nadb I just repasted it and so far it looks it was very good tip :slight_smile: My usual temperatures were 70+ or 80+ Celsius now it is 50+. And I even open all programs I use to have opened. I will see how it goes
